As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.
Some examples:
Python:
To retrieve any attribute form a visible element (e.g.
<h1>tag) you need to use the expected_conditions asvisibility_of_element_located(locator)as follows:attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")To retrieve any attribute form an interactive element (e.g.
<input>tag) you need to use the expected_conditions aselement_to_be_clickable(locator)as follows:attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
HTML Attributes
